LIQUID-DISPENSING DEVICE.

Application filed October 10, 1924.

To all whom it may concern:

Be it known that I, CrrAnLns h'l'. Kinsman, a citizen of the United States, residing at St. Louis, Missouri, have invented a new and useful Liquid-Dispensing Device, of which the following is a specification.

This invention relates to improvements in liquid dispensing devices, and consists in the novel construction thereof hereinafter disclosed.

An object of the invention is to provide in connection with a container a removable top equipped with a pouring spout and provided with vent openings so arranged that the container may be. filled through the pouring spout and the liquid dispensed therefrom without the overflow of the liquid from the Another object of the invention is to provide a dispensing device of the kind mentioned equipped with vent openings so arranged as to permit escape of air when the container of the device is filled, andto admit air when the liquid is dispensed from the container so that the flow will be uniform and steady.

Additional advantages of the structure will be apparent from the following detailed,

description thereof, taken in connection with the accompanying drawing, in which Fig. 1 is an elevation of the device.

Fig. 2 is a vertical section through a portion of the device showing the arrangement of the vent openings.

Fig. 3 is a vertical section further illustrating the arrangement of the vent openig. 4 is a cross section taken on the line 44 of Fig. 1.

In the embodiment of the invention illustrated in the drawing the container of the device is shown in the form of a jar 1 prefe'rably of the well known type commonly used as a fruit jar, and having an exteriorly threaded outlet opening 2 at the top. A cap 3 having a convexed upper section 4 and a threaded lower section 5 is adapted to be removably seated on the threaded portion 2 of the container 1. In order to provide for the convenient manipulation of the cap it is equipped with a knurled rim 6.

The section 4 of the cap is provided with a circular opening 7 in 1ts top wall. The metal cut away to form the opening 7 is utilized for making a retaining ring comprising a vertical flange 8 and a downwardly de- Serial No. 742,790.

flected flange 9. A spout member 10 formed of a rolled sheet of metal having an upward taper, the ends of the metal being pressed together to form a seam 11, projects through the retaining ring 89 between the wall of the flange 8, being driven to a tight fit there in when the large end of the spout is adjacent to the inner surface of the flange 9.

The upper end of the spout 1O is'preferably beveled so as to form a convenient pouring outlet, and the cross diameter thereof is preferably of a size so that the spigot of an ordinary oil pump may be inserted therein for filling the device, it being understood that the present invention is particularly designed for measuring quantities of lubricating oil to be dispensed at filling stations for automobiles.

The spout 10 near the bottom end thereof has a plurality of vent openings 12, said openingsbeing preferably of oblong form with the longest diameter extending vertically. The upper walls of the openings 12 are deflected inwardly forming thelips 13 that act as baffle walls when the device is being filled through the spout 10 to deflect the liquid inwardly and to prevent it flowing outwardly through the vent openings 12.

A shield in the form of a convex cap 14 is fitted over the lower end of the spout around the section of the spout in which the vent openings12 are formed. This cap 14 has a downwardly extending flange 15 that lies beneath the edge of the opening 7 in the section 4 of the cap 3 and is so disposed that the flange 9 of the retaining ring is disposed beneath the lower edge ofthe cap 14, all of the parts being retained in place by a quantity of solder 16 disposed around the lower edge of the spout. This arrangement of the parts and their vmethod of assembly produces a strong joint between the cap 3 and the spout 10, the overlapping flanges 9 of the retaining ring and the flanges 15 of the cap 14 serving to reinforce the joint.

Through the wall of the cap 14 and preferably at a pointdiametrically opposite the pouring side of the spout 10 are ventholes 17 these vent holes being located approximately on a median line of the height of the cap 14. The cap 14 .is assembled with the spout so that the vent holes 17 are out of alinement with the vent openings 12 so as to prevent any of the liquid from splashing outwardly through the holes when the device is being filled. It will be noted alsothat the vent openings are conveniently located so that an operator when pouring may readily place his linger over the vent openings if, for any purpose, he desires to retard the flow of the liquid from the container.

lVhen the device is being filled the air in the container passes outwardly through the vent openings 12 and into the space be.- tween the wall of the spout and the inner wall of the cap 14., from which space it has egress through the vent openings 17. The walls 13 formed at the top of the vent openings 12 prevent any substantial amount of liquid flowing into the space between the spout and the cap 1 1, but what little liquid may enter these openings is trapped in the bottom of the chamber formed by the cap 14: and the wall of the spout and, before it can rise to a point level with the lower edge of the openings 17, it will flowback into the container through the vent openings 12 as the lower edge of the vent openings 12 is below the lower edge of the openings 17. When the liquid is poured from. the device air is admitted in sufficient quantities to provide a steady llow through the vent openings 17 into the chamber formed between the cap 14 and the wall of the spout and thence into the spout through the openings 12.

It will be seen therefore that the chamber formed between the. cap 14 and the spout constitutes a trap for the liquid passing into the container, or being dispensed from' the container, and that the openings 12, arranged as they are in respect of the vent openings 17, permit the liquid to flow back into the spout before the level thereof rises to a point, either in a filling operation or in' a pouring operation, so that it will flow out of the vent openings 17 The device is thus arranged to provide sutlicient air in both filling and pouring operation and at the same time to prevent any outflow through the vent openings from atmosphere formed in the cap 14.

I am aware that the invention may be modified in certain particulars without departing from the spirit and scope thereof. I do not limit myself therefore to unessential details, but what I claim and desire to secure by Letters Patent is 1. A liquid dispensing device comprising a container, a cap for said container, a spout in connection withsaid cap, said spout being provided with vent openings near the bottom thereof and above said cap,

and a vented housing aroundthe .vent openings arranged to prevent liquid frompassing outwardly from the spout either in filling or pouring operations through the vent openings therein.

2. In a liquid dispensing device, a pouring spout adapted to be mounted upon a container, said spoutbeing provided with vent openings therethrough, a housing encircling the spout over the ventopenings, said houslng having a .vent therein that s out of alinement with any one of the vent openings in sa d spout.

3. A liquid dispensingdevice comprising a container, a capadapted to be threaded upon the container, a spout connectedxwith said cap, said. spout havingelongated verticallydisposed vent openingstherein near the lower end thereof, inwardly deflected walls over said vent openings, anda .housing around said spoutand over said vent openings, said housing being providedwith a vent of less diameter than. the vertical length of the openings in said spout.

4. A liquid dispensingdevice comprising a container, a cap adapted to be threaded upon the container, said cap having a circular opening in the top thereof, a retainin x; ring mounted in said opening, atapered spout mounted .in .said retaining ring,- said spout being provided ,with vent openings, a housing having. a flangeextending below the openin in. the can and between the edge alinement with the vent openings in ,the.

spout and intermediate the upper and lower limits of said vent openings in said-spout.

6. A liquid dispensingv device, comprising a container, a spout in, connection with said container, a housing arranged exteriorly of the spout, said housing andsaid spouthaving vent, openings arranged in staggered.

relationship, the vent openings in the housing being of a vertical diameter lessthan the vent openings in the spout.
